Message: 51496 Does wm8731 driver support BF536 in 2008r1?
The bf5xx-pcm.c misses bf5xx_ac97_pcm32_to_frame and bf5xx_ac97_frame_to_pcm32.
I copy it from bf5xx-ac97.c, then it can compile success.
But i cannot play audio and record audio.

No - that codec will not work with the ac97 driver. You are better off looking at the AD1836 driver.

Message: 51605 we dont have any documentation on writing sound drivers. you can refer to the ALSA project:
there is a wm8731.c ALSA SOC codec driver in the kernel, but we've never tested it

Message: 51904 If I choice BF527 and WM8731, it has some error messages.
The bf5xx-pcm.c unreferenced bf5xx_ac97_pcm32_to_frame and bf5xx_ac97_frame_to_pcm32.
